The whole conclusion seems to be just try different things which isn’t great. I love smoothies before a run because I don’t have to chew which seems to help but your results may vary. Also I don’t go the same distances so it might not be as calorie dense.

I do know quite a few people who I run with who do full vegan while training and then consume meat products in preparation of their races, during their race and as some recovery days. It is suppose to be great but I have never done it. I don’t think its for gut health specifically
